customize

Dear developer,

Looking for a way to add a custom list of products available for my customers to add quantities, i came across your plugin.
Unfortunately the result is shown in the image below:

Sorry but since i am a newbie here, can please help me
– where can i add the code necessary to make rows with less height?
– how can i sort by name asc or desc ?

I suspect extra fields are shown and cart is not displayed correctly?

regards
Costas
